APPARATUS FOR REAMING BUNG-HOLES OF BARRELS.

Application filed May 6, 1913.

To all whom it may concern:

Be it known that I, ALBERT E. EAGER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Lnprovements inApparatus for Beaming Bung-Holes of Barrels, of which the following is aspecification.

This invention relates more particularly to apparatus for reaming thebung holes of barrels after the preliminary boring, in order to enlargeand taper the opening for the reception of a suitable bung; but each ofthe improvements composing the invention is intended to be secured forall the uses to which it can be applied with or without modification.

In reaming 'out a bung hole there is danger that the cuttings consistingof'fine shavings or particles of wood dust may enter the barrel; and,being difficult of removal, they are liable to remain (if they once getinside) and so to constitute a very obj ectionable litter and tocontaminate the materials which the barrel may eventually receive. Inaccordance with the present invention said shavings or fine particlesare as formed removed by means of a current of air (produced by anexhaust) in a manner efiectually to prevent entrance into the barrel.

The invention, which is particularly pointed out in the hereinafterwritten claims, will now be described in connection with theaccompanying drawings, it being premised that details are given by wayof example and that additions, subtractions and other modifications canbe made indefinitely so long as the substance of any one or more of saidclaims is taken.

ing tool has a hollow conical body a tapering toward its lowerend so asto fit with equal closeness the gradually enlarging hole as it entersthe same. On the exterior of the reamer body a is a series of spacedmarks 6 (shown as circumferential grooves) which indicate to theoperator the extent to which the tool has entered and consequently thesize of the bung hole at, any stage of the reaming operation. 7

The reamer body a has a slightly tapering interior space 0 open at topand bottom so as to form an air withdrawing passa e. At the lower endcommunication is estcblished between this interior space and theexterior by the channel (Z in line with the tool axis. Lateral channels6 alsopass through the upper walls from without to the hollow interior.Other channels may well be placed at the lower end of the tool, asindicated in dotted lines at cl.

Throughout a portion of its length the wall of'the reamer body a isprovided in its peripheral wall with a longitudinally disposed slot 7;within which and projecting at its cutting edge beyond the reamer bodyis a longitudinally disposed knife 9. The ends 9 and g of this knife areclamped one of them under the overhanging lip of a clip h secured by ascrew it, and the other under the lip of the wedge i; which isexteriorly threaded and held against the knife end 9 by an interiorlythreaded collar Thus the knife is held firmly in place and is yet easilyloosened for adjustment or removal. The collar j is held from turning inuse by a set-screw j.

The upper end of the reamer body a is exteriorly threaded to receive thecollar j and also to enter the correspondingly threaded lower end of atubular shaft is, which shaft is also laterally perforated at 70 inorder to form with the channels 0 throughways for the passage of air tothe interior of the reamer body at its upper portion At 7c areadditional air inlets. Surface grooves Z extending lengthwise of thereamer body a permit air to pass The lower end of the reamer body a issquared at a for the reception of a wrench.

The tubular shaft Z2 is mounted to rotate and also to slide freely inbearings m, m and m of the bracket 71. A drive shaft 0 driven by thedrive pulley 0 is likewise journaled in the bracket n and carries thebevel gear 20 meshing with the bevel gear 3? whose nave is connected bya spline and groove or other equivalent connection with the tubularshaft is so as to turn the latter while allowing it to slide freelythrough the gear.

To the shaft is rota'tably secured a collar g; and to this collar isattached the shift lever provided with a counterweight r and fulcrumedby means of the intermediate link 8 to the bracket n, whereby theoperator may lower and raise the shaft 70 and reaming tool to bring thelatter into and out of working position.

The upper end of the shaft 70 rotates within a tube 6 which rests at itslower end upon a plate to supported by the bracket 11. The air tube 25flares outwardly at its upperend in the form of a funnel, as at o; wherea number of peripheral openings 0 are provided for the entrance of airfrom the outside.

With the large upper extremity of. the funnel 'v is connected the lowerend of the exhaust pipe to of much larger diameter than the air tube t,the tubular shaft is and the reaming tool; and at the upper extremity ofthe exhaust pipe w is arranged the exhaust fan w driven by the driveshaft y and the drive pulley a.

The operation is as follows: A barrel to be reamed having beenpositioned beneath the apparatus with its already bored (but unreamed ornot sufliciently reamed) bung hole in line with the reaming tool, theoperator, by means of the shift lever, lowers the reaming tool into thebung hole, gradually entering the same until by means of the grooves 5he perceives that the diameter is sufficiently large. As the rapidlyrotating tool enlarged the hole, airenters the tool both through theslot f and the bottom opening in end (Z (also through side channels 62,if used) and the fine shavings or particles of wood dust are caught bythe air current and are carried therewith into the tubular shaft 70.Here they are caught by the additional air entering through the holes 70and 7a and are hurried into the funnel portion Q, whence, assisted bythe air entering at '0, they are borne through the exhaust pipe to anddischarged through the exhaust fan so.

The number and size of the openings cl, 7r, 7c" and o and the diameterof the parts a, is, t, o and w are best so proportioned that a steadyand continuous draft is maintained at all points; so that the progressof the upwardly traveling particles of wood dust is uniform and there isno settling back or 001- lecting in eddies or the like.

The apparatus will operate in a horizontal or in an inclined position;but the vertical arrangement is considered most advantageous.
